The rapidly expanding co2 does get very cold though. It’s not any different from freezing things with compressed air cans.

I don’t hover, know which would absorb more heat per pound though. Someone who knows more math than I can do it though.

If I’m reading Wikipedia correctly, it takes 348 Joules of heat to boil a gram of CO2.

Water is 2257 Joules per gram. As long as you don’t need anything cooled under 100C, water is the way to go for cooling. It’s also a hell of a lot cheaper and easier to deal with than liquid CO2.
